Abstract

Low-cost housing should not only satisfy functional, spatial or urban requirements but should also create comfortable indoor environments. For economic and practical reasons we need to work within the current system of low-income construction practice to achieve the required indoor thermal environments. At the Du Noon settlement approximately 20km north of Cape Town, South Africa, low-income housing is provided by means of a subsidy system of R17 500 per new home owner (U$2613). The core starter house (20m²) costs R10 000 while the site and services cost R7500. The thermal performances of five different construction methods used at Du Noon have been assessed by means of an empirical method developed by the National Building Research Institute of South Africa (Wentzel 1981). The concrete block and steel sheet roof construction method, which is currently the model for the rest of the development of 1000 houses, has been further analysed by means of on site temperature measurements to determine and verify problem areas. This paper sets out to determine how the above construction method can be adapted or manipulated to achieve acceptable comfortable indoor conditions.
